I just published my first watchfaces at Connect IQ store: WeatherBarsH and WeatherBarsV.
Your advices and proposals are very welcome!
WeatherBarsH and WeatherBarsV is are free watch faces with bright and easy 3 day weather forecast in a novel horizontal bar chart and more traditional vertical bar chart formats respectively. Time font and icons are anti-aliased.
These are just weather watch faces yet, they cannot indicate your HR, steps etc. at this moment. They provide 100% support for Garmin Fenix 6X, 6X Pro and Sapphire watches with 280*280 screen resolution and they need the latest CIQ v3.2. Fenix 6 and 6S may have some slight differences and not fully optimized, but still should work. More Garmin smartwatches may be added in the next release.
Data available for both watchfaces:
- Date in the (day of week) dd . mm format;
- Week and day-in-a-week numbers;
- Notification status;
- Weather from Garmin servers: current conditions and 3 days forecast in Celsius and Fahrenheit (no API key is required, but your smartwatch should be connected to your phone via Bluetooth and hence has connection to Internet);
- WeatherBarsH indicates precipitation probability with color: green for dry condition. blue for low, yellow for moderate and red for high precipitation probability;
- Smartwatch Status (Bluetooth, Notifications, DND, Alarms);
- Dual time (2nd Time Zone);
- These watch faces support English language only yet.
I plan to bring these watchfaces to more devices, adding more options like wind speed in mph, changing status icons to steps and floors numbers etc.
